Hendrik Buschmeier

I am a PhD-student and research associate in Stefan Kopp’s Social Cognitive Systems Group at the Faculty of Technology, Bielefeld University.

I am working in the research project KOMPASS (funded by the German Ministry of Education and Research, BMBF), where I model ‘socially cooperative’ dialogue behaviour for a virtual assistant for elderly and cognitively impaired people. I have previously worked in the projects ‘Rhythm and Timing in Dialogue’ and ‘Dialogue Coordination for Sociable Agents’ (both DFG-funded).

Research Interests

My general area of interest is computational modelling of the representations, processes, and behaviours underlying the human capability for interacting in dialogue. In particular, I am interested in the issue of how a joint understanding can be achieved among autonomous conversational agents (human or artificial), including questions such as: How can an agent know whether and how its utterances are understood by its interaction partner? How can it know what the reasons for problems in understanding are? How can an agent design and adapt its utterances and behaviours so that mis-understandings are repaired and future ones avoided? How do agents coordinate their behaviour, cooperate to achieve joint goals, and collaborate on the construction of a joint understanding? Finally, I am interested in how a joint understanding can be achieved in an effective yet efficient way, such that a model is plausible from a cognitive point of view, and practical from a computational point of view.
